Franz, Thanks to you and your colleagues for the rapid response. I'll look forward to the corrected file. And I'll be reading up on Etienne Corteel's work. When you say "a compact circular ... array", I gather that you mean an array with the loudspeakers facing outwards? We can do that too.

There should be 9 non-zero channels. It seems Winfried and I we were so pleased about the nice "compression" that we did not check the compressed file... we will fix this. Jörn is right: the file is for radiation synthesis using compact circular loudspeaker arrays or wave-field synthesis (cf. e.g. Etienne Corteel's paper on that).
